Description:
Cascading failures are a concern for site reliability engineers (SREs) because they often stem from positive feedback and grow over time. In this course, you'll examine the various cascading failure triggers, such as overloads, CPU, and memory issues. You'll also explore the resource exhaustion issues resulting from cascading failures and the adverse effects on overall performance and stability.
You'll outline steps to prevent server overloads, ensure efficient queue management, deal with latency, and manage slow startups. You'll explore terms such as ""load shedding"" and ""code retries."" You'll also identify the benefits of setting deadlines and how propagating cancellations can reduce or eliminate unneeded work and preserve resources for other needs. Finally, you'll outline the steps involved in testing cascading failures and in addressing them immediately.

Description:
Site reliability engineers (SREs) are typically responsible for preventing and managing overloads. A common misconception is that overloads only affect computer systems. However, overloads also comprise types of occupational stress, which invariably negatively affect an organization.
In this course, you'll explore the fundamental concepts and methods involved in managing overloads. You'll start by identifying operational load types and how they relate to performance. You'll then outline how to mitigate workloads and prioritize work before recognizing the specific consequences of overloads. You'll then describe how to manage client-side traffic using per customer limitations and client-side throttling. You'll examine tools such as criticality values and utilization signals. Finally, you'll explore approaches used for handling overload errors and learn how to identify issues caused by loads associated with connections.
